Abstract

Objective: Palatability of medication is an important factor for adherence, especially in pediatric populations that tend to use oral suspensions for antibiotic therapy. Our study is the first to evaluate the impact of taste on prescribing patterns of antibiotic suspensions. The objective was to determine if taste testing common antibiotic suspensions altered prescribing patterns of medical residents, through data extracted from the electronic health record.

Methods: After assessing 5 "primer" tastes (sweet, salty, bitter, sour, umami [savory]), residents were randomized to sample 6 antibiotic suspensions to rate their taste perception. A 12-month retrospective and prospective analysis of outpatient prescribing practices of the residents followed, and the results were compared to the resident cohort randomized to no taste test.

Results: The 43 residents prescribed 207 liquid antibiotic prescriptions for 176 patients, with no difference in patient characteristics between residents in the taste test versus non-taste test group. Although amoxicillin was most preferable and amoxicillin-clavulanate least, the only significant finding was a greater prescribing rate of cefdinir among those who had tasted it and an inverse relationship between cephalexin taste preference and percentage prescribing amoxicillin in the taste group. Residents who tasted were poor in identifying primer tastes, but this did not impact prescribing patterns.

Conclusions: Among 6 commonly prescribed antibiotic suspensions, amoxicillin remains a highly preferred taste among prescribers. Interestingly, after the taste test there was a significantly greater prescribing rate of cefdinir among those who had tasted it and somewhat lower prescribing rate for amoxicillin-clavulanate.
